DESCRIPTION:A brief introduction to radiosondes covered the measurement te
 chniques\, processing and their uncertainties.  Almost 40% of radiosonde 
 stations now provide high vertical resolution reports in BUFR format along
  with the position of each level. Accounting for the radiosonde drift in N
 WP systems improves the upper level fit between radiosondes and model fiel
 ds. Radiosonde descent data (after balloon burst) looks useful but will ne
 ed extra quality control.  ECMWF observation-minus-background statistics 
 show some variations in quality between different radiosonde types and als
 o clear variations with latitude. Larger differences in the tropical strat
 osphere are probably related to gravity wave activity.\n\nWebinar speaker\
 n\nBruce Ingleby\, ECMWF Senior Scientist\n\nBruce Ingleby works on the pr
 ocessing and assimilation of in situ observations.  He has over 30 years 
 experience in many different aspects of data assimilation. He worked at th
 e UK Met Office and has been at ECMWF for the last five years.\n\nhttps://
